The influence of demographic parameters was explored by univariable logistic regression analyses.

^aD0 is the day of vaccination within this study.

^bOther daily food like rice, corn, fish.

^cBCS ranged from 1 to 5 and was categorised as poor for scores lower than 3 and good for scores of 3 or higher.

^*p-value shown in bold represents p ≤ 0.25; these variables were used in the subsequent multivariable logistic regression analysis.
